My child is 6 months old, we have started giving external food in form of liquid and paste. Twise a a day along with milk breast feeding. Even after this he wakes up around 4-5 times in night and when my wife gives breast feeding he goes to sleep. Is this a normal ? do we need to feed him more ?he wears diaper in night
